Power Train
Performance: Hydrostatic Transmission
- Engine speed is automatically maintained to match the power requirements of the application. It also offers independent power and control of each track, for fast acceleration and on-the-go direction changes.
- Quick response to varying loads for shorter cycle times
- Traction control allows better traction when working in poor underfoot conditions
Unsurpassed Maneuverability
- Intuitive controls help you work in tight areas
- Power turn feature provides power to both tracks while working in confined area
- Counter-rotation provides quick steering corrections during side loading applications
Fuel Economy
- Eco Modes achieve significant fuel consumption reduction by allowing the engine to run at lower speed whenever possible, and rapidly increasing speed when power is needed. Designed to save fuel in light or medium duty applications, the extremely fast engine response allows these modes to be used even in power demanding applications and eliminates the need to constantly shift into and out of Eco Modes.
- Operators can either select the “Reverse only” or “Forward and Reverse” mode
- Can help save from 5 percent up to 22 percent of fuel depending on the application
Undercarriage
Updated Undercarriage Design
The new undercarriage design improves durability and increases stability to allow smoother ride and excellent finish grading performance. You can grade faster, while still producing a top quality finish grade at the first pass.
Choice of Undercarriage Configurations to Meet Your Application
- Track frames are available in extra long (XL) or low ground pressure (LGP) configurations:
- XL undercarriage for most applications where flotation and side stability are not extreme
- LGP undercarriage for soft underfoot conditions where additional flotation is required
Track Selection
- Caterpillar offers a choice of two undercarriages - Sealed and Lubricated Track (S<) and SystemOne™. Matching the correct undercarriage to the application and soil conditions will deliver the lowest costs per hour.
- Sealed and Lubricated Track (S<) Undercarriage - For aggressive impact applications, with the necessary wear material for long life - Designed to ease disassembly for bushing turn service to maximize wear life
- SystemOne Undercarriage
Work Tools
New Bulldozer and Wider Blade Design
- Both XL and LGP blades are now wider; this improves finish grading productivity by covering more ground at each pass
- Strong design allows Cat blades to stand up to the most severe applications
- Large spherical linkage bearing for easier blade removal and designed for the life of the machine
New Variable Pitch Angle Tilt (VPAT) Blade
The versatility of the VPAT Blade gives the D6K2 the ability to take on a variety of applications and material conditions, such as finish grading, spreading material or backfilling. This blade allows the operator to adjust the blade lift, angle and tilt simultaneously. The blade pitch adjustment is made easier, which can help increase your productivity.
New Foldable Blade Option
Designed to facilitate transportation without blade removal, foldable blades reduce the overall shipping width. The blade can be easily folded without the need for tools.
Integrated Technologies
AccuGrade
- This dealer installed machine control and guidance system enables operators to cut and fill to grade with increased accuracy, minimizing the need for traditional stakes and grade checkers. Caterpillar offers a choice of:
- AccuGrade Laser - for two dimensional flat type of work
- AccuGrade Global Navigation Satellite System - for three dimensional cut to contour work
- Universal Total Station - for fine and finish grade applications
AccuGrade Ready Option (ARO)
This option provides the pre-assembly that is required to make the AccuGrade installation quick and easy.
